Title: Improvements in total-printing mechanism for use in recordcard-controlled statistical machines
Filed: 1923-03-08
Abstract: 217,523. Vox Maschinen Akt.-Ges., and Vogelsang, W. March 8, 1923. Statistical machines; printing totals; displaying and printing sub-totals.- In adding-mechanism for record - card - controlled statistical machines differential actuating sectors 3 are rotated by the correct amount to set type wheels 11 and on their return movement the pinions 16 of the totalizing-counter wheels 17 are depressed into mesh with these sectors so that the item is added to the counter. The sectors are loosely mounted on a shaft 2 and are held against the action of their springs 4 by a universal bail 5 controlled from a cam-shaft 38. Each sector meshes with a pinion 9 of eleven teeth integral with a type wheel 11 and a ratchet wheel 10 of eleven teeth the wheel 11 having types 0-9 and a blank space. Co-operating with each ratchet wheel is a spring-controlled detent 33 normally latched up by a spring catch 34. The items set up on the wheels 11 are printed on a strip P by means of an inking-ribbon F, and a platen 57 mounted on a frame 53 which rocks about. a shaft 54 and is controlled from the cam-shaft 38, this frame 53 also carrying paper feed rollers 90, 91 of which 91 has a ratchet feed. The numeral wheels 17 and their wheels 16, of ten teeth, are loosely mounted upon a shaft 13 carried by arms 14 on a shaft 15 controlled by an item-printing cam 39 or by a total-printing cam 40, feathered on the shaft 38, Fig. 2, according to the position of a special lever 44. Upon operation of the machine the cam-shaft 38 is rotated, the bail 5 is lowered and the sectors 3 are rotated by their springs 4. The detents 33 are released by perforated record-cards causing the retraction of rods 78 and the catches 34 so that the wheels 11 and sectors 3 are arrested and the item is set up on the type-wheels. The cam shaft 38 then operates to rock the frame 53 and print the item. At the same time the shaft 15 is rocked to depress the pinions 16 into mesh with the sectors 3. A bar 36 controlled from the shaft 38 is then raised to relatch the detents 33 and release the ratchets 10, after which the bail 5 is raised to restore the actuating sectors 3, whereupon the item is added to the wheels 17 which are then raised to normal position by the shaft 15. To print a total the lever 44 is moved to place the shaft 15 under the control of the total-printing cam 40 and the shaft 38 is rotated without the insertion of a recordcard. After the actuating sectors have been moved one tooth and have turned the type wheels to the zero positions, the pinions 16 are depressed into engagement with the sectors, which are then rotated until the various numeral wheels 17 are arrested at zero by lugs 70 thereon abutting against a comb 71. This comb is carried in extensions of the arms 14 and during normal operations the lugs 70 pass through the apertures of the comb, but when the lever 44 is moved to place the shaft 15 under control of the cam 40 the comb 71 is moved laterally so that the solid part of it comes into the paths of the lugs. The total thus set up on the type wheels is then printed, the pinions 16 raised, and the sector 3 subsequently restored so that the totalizing counter remains zeroized. Where subtotals are required, to reinstate the figures on the counter, immediately after printing the lever 44 is reversed to place the shaft 15 under control of the itemprinting cam 39, whereby the pinions remain down in mesh with the actuating-sectors 3 until after the sectors are restored. Controlling indication and printing of zeros.- Horizontally movable arms 46, Fig. 3, normally prevented from movement to the left by a stop 48 connected to the lever 44 and by parts 96 on them, have each lugs 95, 97 co-operating with the appropriate actuating-sector 3 and with a notch 85 in the corresponding totalizing-counter wheel 17, Fig. 1, respectively, All wheels corresponding with ciphers to the left of the first significant ngure will be in zero position and on movement of the stop 48 immediately the lever 44 is moved to total-taking position, the corresponding arms 46 will move so that their lugs 97 enter their notches 85 and the lugs 95 arrest the actuating- sectors and type wheels from all movement, so that the blank spaces on the type wheels are presented to the. paper P. The arm 46 corresponding with the first significant figure will not move since its shoulder 97 cannot enter the notch 85 and this arm will also hold all arms to the right, Fig. 3. Transfer mechanism. - Transfer - actuating sectors 18<a>, integral with arms 18<b>, 18<c> are normally held against their springs 22 by a universal bail 19 and shoulders 29 on levers 24 with the. last total showing in the window 43. During restoration of the actuating-sectors and while the pinions 16 are still in engagement with them, if a wheel 17 passes from 9 to 0 a pin 26 thereon rocks the corresponding lever 24 to remove a stop face carried thereby out of the path of the sector 18<a> of next higher denomination, the lever 24 being latched in this position by co-operation of a tooth 27 and a spring latch 30. After the item has been added to the counter and the pinions 16 are again in mesh with the transfer sectors 18<a>, the bail 19 is lowered so that all sectors 18<a> the levers 24 of which have been latched are rotated slightly by their springs 22 to effect transfer. Thereafter the bail 19 is raised and a bail 31 disengages the latches 30 from the teeth 27.
